Thank you for your answers.
I don't find any information about Joomla for Linux. I'll post the question in the French Joomla forum.
There are other tools I need to work, such as Ranking Tool Box, Swishmax, Flash MX, Dreamweaver, Kompozer, and a few others...
Instead of Adobe (Photoshop 7, Illustrator 10), I know I can use Gimp and Inskape for Linux, but :
- it will take a long time to be able to work as fast with them as now with Adobe.
- the question of ICC profile is very important for this work, and I have not tested Gimp and Inskape.
In conclusion, I think I have to install Suse on a third hird drive (that means change my power supply), with wine, and try all these softwares without windows.
Thanks a lot. (and sorry for my poor english)
